Problems solved by technology

[0017] In addition, when the installation error of the upstream scraper 101a and the downstream scraper 101b with respect to the detection roller 111 and the reference roller 112 is large, the amount of twisting and deformation of the leaf spring 118 is insufficient for the error, so the upstream scraper The top ends of the plate 101a and the downstream side scraper 101b cannot be in close contact with the surfaces of the detection roller 111 and the reference roller 112 across their entire range, resulting in one-end contact
Originally, when installing the upstream side scraper 101a and the downstream side scraper 101b, if the installation position can be adjusted, the installation error can be reduced and one-end contact can be prevented. However, in this case, the process will be increased, so the manufacturing process will be improved. cost

Embodiment Construction

[0034] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0035] figure 1 It is a configuration diagram showing the medium thickness detecting device of the foreign matter removing device having rollers in the first embodiment of the present invention.

[0036] 20 in the figure is a medium thickness detection device in this embodiment, which is used to detect the thickness of the medium 32 in a medium processing device such as a banknote identification device installed in an automatic transaction device, an automatic vending machine, a money changer, a game machine, and the like. Here, the above-mentioned medium 32 is, for example, banknotes, but it may also be vouchers such as beer coupons, gift certificates, and commodity certificates; securities such as traveler's checks, checks, and stocks; facility use tickets such as admission tickets; tickets; Passbook, etc., can be of any kind.

[0037] Here, for convenien...

Abstract

The invention provides a foreign matter removing device of roller, which can be rotarily mounted with a bidirectional scratch board, wherein only one side of the bidirectional scratch board is contacted to the roller surface regardless the rotary direction of the roller, so that the foreign matter removing device can reliably remove the foreign matter on the surface of the roller and can reduce the load torque.

Description

technical field [0001] The invention relates to a foreign matter removing device for a roller. Background technique [0002] Conventionally, ATMs (Automatic Teller Machine: cash automatic teller machines), CDs (Cash Dispensers: cash automatic teller machines), etc. Automatic transaction devices and money changers, or automatic vending machines installed in shops or roadsides, etc., are equipped with a medium identification device for determining the authenticity of securities such as banknotes or the type of medium. In addition, a technique for detecting the thickness of a medium for discriminating the authenticity of a medium such as a banknote in this medium discriminating device has been proposed (for example, refer to Patent Document 1). [0003] In this case, when the medium passes between a pair of rollers arranged in the medium conveyance path, the thickness of the medium is detected by measuring the vertical movement amount of one roller. However, if the roller is ...
